Audit Sampling Flashcards
The risk of incorrect acceptance and the likelihood of assessing control risk too low relate to the
Effectiveness of the audit
When performing a substantive test of a random sample of cash disbursements, an auditor is supplied with a photocopy of vendor invoices supporting the disbursements for one particular vendor, rather than the original invoices. The auditor is told that the vendor’s original invoices have been misplaced. What should the auditor do in response to this situation?
Reevaluate the risk of fraud and design alternate tests for the related transactions
Which of the following statements about audit sampling risks is correct for a nonissuer?
Nonsampling risk can arise because an auditor failed to recognize misstatements
The likelihood of assessing control risk too high is the risk that the sample selected to test controls
Does not support the auditor’s planned assessed level of control risk when the true operating effectiveness of the control structure justifies such an assessment
In planning a statistical sample for a test of controls, an auditor increased the expected population deviation rate from the prior year’s rate because of the results of the prior year’s tests of controls and the overall control environment.
The auditor most likely would then increase the planned
Sample Size
The sample size of a test of controls varies inversely with
Tolerable rate
To determine the sample size for a test of controls, an auditor should consider the tolerable deviation rate, the allowable risk of assessing control risk too low, and the
Expected deviation rate
Which of the following factors is/are considered in determining the sample size for a test of controls?
Expected deviation rate ,Tolerable deviation rate and the allowable risk of assessing control risk too low
For which of the following audit tests would a CPA most likely use attribute sampling?
Identifying entries posted to incorrect accounts
In statistical sampling methods used in substantive testing, an auditor most likely would stratify a population into meaningful groups if
The population has highly variable recorded amounts
Stratified mean per unit (MPU) sampling is a statistical technique that may be more efficient than unstratified MPU because it usually
Produces an estimate that has a desired level of precision with a smaller sample size
When using classical variables sampling for estimation, an auditor normally evaluates the sampling results by calculating the possible error in either direction
Precision
The use of the ratio estimation sampling technique is most effective when
The calculated audit amounts are approximately proportional to the client’s book amounts
Which of the following is the primary objective of probability proportional to sample size
To identify overstatement errors
Which of the following statements is correct concerning probability-proportional-to-size (PPS) sampling, also known as dollar unit sampling?
The auditor controls the risk of incorrect acceptance by specifying this risk level for the sampling plan
